which element does use the APU controlled (APU) to monitor the supply oil filter. dual pressure sensor P3/P4. Dual pressure sensor P1/P2. Scavenge oil temperature sensor.

which does occur if the APU oil cooler gets clogged. an APU protective shutdown occurs during attendant mode only. a bypass valve opens to let the oil go around the cooler. an EICAS advisory message without APU shutdown.

the APU speed will vary as a function of. Inlet (ambient) temperature. inlet pressure. pneumatics demand.

the APU oil level sensor sends data to. flight control computer (FCC). APU controller (APU). Common corre system (CCS).

how many scavenge oil filter elements are there. one for both APU starter generator. three,two active in each APU starter generator and the other one backup. two,one for each APU starter generator.

If the APU oil temperature is more than the permitted limits,then. APU LIMIT, EICAS caution message shows in attendant mode. APU LIMIT, EICAS warning message shows in unattendant mode. APU controlled (APU) shows a simulated temperature of -25ºF.

where does the APU controlled (APU) get oil pressure data from. P2 sensor, during normal operations. With the difference between P2 vs P1. P1 sensor, in attendant mode and P2 sensor during unattended mode.

APU air inlet door actuator takes electrical power from. left ram fan motor controller (RFMC). APU battery bus. Main battery bus.

what is used at the oil cooler to decrease the oil temperature. outside air from side ducts of air inlet duct. discharge air from the first turbine stage. fuel from the left main aircraft tank.

which are the internal APU parts. one stage centrifugal compressor,axial flow annular combustor and four stages axialturbine. one stage centrifugal compressor,reverse flow annular combustor and two stagesaxial turbine. two stage centrifugal compressor,reverse flow annular combustor and one stages axialturbine.

in the APU Unattended mode, a clogged scavenge filter causes. protective shutdown. deprime valve opens to decrease oil drag. Eicas messages only.

APU air inlet door position switch supplies a signal the open to. electronics control box (ECB). APU controller (APUC). common core system (CCS).

Where are the supply and scavenge oil pump located. in the gearbox. next to the fuel module. between both APU starter generator (ASG).

If the APU air inlet door actuator fails,how could you move it. manually to open position only. manually to open or closed positions. hydraulically to open or closed positions using an external hand pump.

the APU air inlet door moves external air to. combustion and cooling. combustion only. combustion,cooling and pneumatic system.
